Diodes Incorporated ZXMS6001N3TA

Overview

ZXMS6001N3TA from Diodes Incorporated is a 60V N-channel self-protected low-side IntelliFET™ MOSFET in SOT223 package, designed for 5V µC-compatible switching. It delivers 675mΩ R_DS(ON) at 5V gate drive, 1.1A continuous drain current (T_A = +25°C, large copper), and integrated overtemperature, overcurrent, active-clamp overvoltage, and ESD protection. Used as a relay replacement in automotive lamp/motor control.

For engineers reviewing the ZXMS6001N3TA datasheet, ZXMS6001N3TA pinout, ZXMS6001N3TA application, or ZXMS6001N3TA equivalent, key selection criteria include its 550mJ unclamped inductive energy rating, thermal shutdown with auto-restart, load-dump protection up to 80V, and linear-mode current-limiting behavior that deactivates below low V_DS to minimize conduction loss.

Technical Context

The ZXMS6001N3TA integrates monolithic protection circuitry including active-clamp overvoltage limiting (V_DS(AZ) = 60–75V), thermal trip at +150°C with +8°C hysteresis, and current-limit activation above 5V V_DS. Its input threshold (V_IN(TH) = 1.0–2.5V) ensures compatibility with 3.3V/5V logic.

It operates in linear mode only during fault conditions: current-limit protection deactivates below ~5V V_DS, allowing full-rated conduction without restriction during normal operation. Maximum DC current is determined solely by PCB thermal design-not protection thresholds-enabling 1.1A with optimized copper layout.

Key Specifications

Pinout & Package

SOT223 (Type DN) package with exposed source-tab thermal pad; tab electrically connected to Source pin and must be isolated from Drain. Recommended mounting on ≥6 cm² copper area (33% to tab, 66% to Drain pin) for optimal thermal performance.

FAQ

What is the maximum continuous drain current for ZXMS6001N3TA at 85°C ambient?

At T_A = +85°C with large copper area (Note 6), the maximum continuous drain current is 825mA at V_IN = 5V. This derating reflects thermal limits of the SOT223 package and PCB layout - not protection circuit activation - and assumes 6 cm² copper coverage with defined source/drain allocation.

Does ZXMS6001N3TA require an external freewheeling diode when driving inductive loads?

No. The device integrates a body diode rated for 2.0A continuous and 3.3A pulsed source current, and its active-clamp overvoltage protection (V_DS(AZ) ≤ 75V) safely handles inductive flyback without external components. External diodes are unnecessary unless peak reverse recovery stress exceeds 550mJ E_AS.

Can ZXMS6001N3TA be used with 3.3V microcontroller GPIOs?

Yes. Its input threshold voltage (V_IN(TH) = 1.0–2.5V) and low input current (≤335µA at 5V, scaling linearly) ensure reliable turn-on with 3.3V logic. Full R_DS(ON) is achieved at V_IN ≥ 4V, so 3.3V operation yields slightly higher on-resistance but remains within functional specification.

How does the thermal shutdown behave during sustained overload?

When junction temperature exceeds +150°C, the device shuts off and automatically restarts once temperature falls by ≥8°C. During repeated faults, this cycle limits average power dissipation and prevents permanent damage - but continuous cycling indicates inadequate PCB thermal design or excessive load demand beyond steady-state ratings.
